Digital Shoreline Analysis System (DSAS)
Computer Software for Calculating Shoreline Change (or positional change of a boundary over time)
The Digital Shoreline Analysis System (DSAS) is an add-in to Esri ArcGIS desktop v. 10.4-10.6 that enables a user to calculate shoreline rate-of-change statistics from multiple historical shoreline positions. It provides an automated method for establishing measurement...
Digital Shoreline Analysis System (DSAS) version 5.0 user guide
OverviewThe Digital Shoreline Analysis System (DSAS) is a freely available software application that works within the Esri Geographic Information System (ArcGIS) software. DSAS computes rate-of-change statistics for a time series of shoreline vector data. DSAS version 5.0 (v5.0) was released in December 2018 and has been tested for compatibility...

Comparing methods used by the U.S. Geological Survey Coastal and Marine Geology Program for deriving shoreline position from lidar data
The U.S. Geological Survey Coastal and Marine Geology Program uses three methods to derive a datum-based, mean high water shoreline on open-ocean coasts from light detection and ranging (lidar) elevation surveys. This work compared the shorelines produced by the three methods for two different surveys: one survey with simple beach morphology, and...

UAS-SfM for coastal research: Geomorphic feature extraction and land cover classification from high-resolution elevation and optical imagery
The vulnerability of coastal systems to hazards such as storms and sea-level rise is typically characterized using a combination of ground and manned airborne systems that have limited spatial or temporal scales. Structure-from-motion (SfM) photogrammetry applied to imagery acquired by unmanned aerial systems (UAS) offers a rapid and inexpensive...
Sturdivant, Emily; Lentz, Erika E.; Thieler, E. Robert; Farris, Amy S.; Weber, Kathryn M.; Remsen, David P.; Miner, Simon; Henderson, Rachel E. Shoreline change as a proxy for subaerial beach volume change
It is difficult and expensive to calculate changes in sediment volume for large sections of sandy beaches. Shoreline change could be a useful proxy for volume change because it can be collected quickly and relatively easily over long distances. In this paper, we summarize several studies that find a high correlation between shoreline change and...
Farris, Amy S.; List, Jeffrey H. Using topographic lidar data to delineate the North Carolina Shoreline
In North Carolina, shoreline change rates are an important component of the state's coastal management program. To enhance methods of measuring shoreline change, the NC Division of Coastal Management (DCM) is considering using mean high water (MHW) shorelines extracted from lidar data together with traditional wet/dry shorelines digitized from...
